In the period of vigorously promoting ecological civilization construction in China at present, pollution prevention and treatment technology and ecological restoration technology are one of the key national requirements.
In the processes of domestic sewage treatment, ecological treatment of river channels, black and odorous river channels, reservoirs, lake surfaces and large watershed river channels for eliminating five types of inferior water quality, drinking water source improvement and aquaculture, the water body must be oxygenated to degrade and remove pollutants.
The current oxygenation methods comprise a mechanical physical method, a chemical method, a biological method and a natural form method. The mechanical and physical method includes the steps of micro-hole of blower, perforation, aeration, water spraying, stirring, turbine aeration, jet flow, etc. The oxygen increasing needs to be achieved by means of mechanical and electric driving of a fan, stirring rotation and air mixing contact. For example, the jet aerator device disclosed in the chinese utility model patent No. ZL87214816 (No. CN87214816U) is composed of a water pump, a hydraulic jet element and a pipe, the water pump is mountable on the ground, the hydraulic jet element is disposed under the water, the hydraulic jet element is provided with a vent pipe, the air is sucked from the vent pipe and mixed with the jet, and is ejected out under the water surface with a certain pressure and speed in a conical flow shape, so that the oxygen in the air can be fully contacted with the pool water and gradually dissolved in the water, thereby achieving the purpose of aeration.
The chemical oxygen increasing mode has the defects that chemical oxygen increasing agents need to be continuously added, the cost is higher, the chemical oxygen increasing agents are unrealistic to control the large watershed water body, and the chemical oxygen increasing mode needs to be added after one-time addition, and is very troublesome; the biological method carries out photosynthesis through algae, fungi, waterweeds and the like in microorganisms to increase oxygen, and needs enough water, enough area and enough water detention time, but for a flowing water body, as the water area and the flowing water quantity of a treatment section are large, when the water speed reaches three meters per minute, the flowing algae are difficult to breed, the water oxygenation is difficult to achieve by means of biological oxygen absorption, the seasonality of aquatic plants is strong, and the maintenance is also complicated; the purpose of oxygenation is achieved by building a water retaining dam in a natural mode, the potential energy of water is mainly used for drop aeration, the mode can cause the problems of flood drainage, waterlogging drainage, damage to the integrity of river channel circulation, blockage of water transportation channels and the like, and the oxygenation effect is poor and is not suitable for treatment of large-basin river channels.
Therefore, further improvements to existing oxygen increasing devices are needed.

The technical problem to be solved by the invention is to provide an oxygen increasing device which can achieve the purpose of increasing oxygen in a water body without additional power sources such as a water pump and the like aiming at the current situation of the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows: an oxygen increasing device, comprising:
a flow guide sleeve having a flow passage therein and having a water inlet and a water outlet in fluid communication with the flow passage, wherein the water inlet is upstream of the water outlet along a flow path of the water flow and the flow passage is tapered along the flow path of the water flow;
the air guide pipe is vertically arranged and is arranged to be fixed relative to the flow guide cover, the upper end of the air guide pipe is provided with an air inlet, and the lower end of the air guide pipe is provided with an air outlet; and
